NOAA's Climate Prediction Center projected Thursday that 13 to 20 named storms would develop over the Atlantic Ocean during the season, which begins June 1 and lasts through November. As many as 11 could become hurricanes, and up to six of those could be major hurricanes with winds of 111 miles per hour or more.

In the typical year, there are only three major storms.

The warning, coming after the monster tornado that devastated Moore, Okla., is fueling fears that the U.S. is in for more pummeling from extreme weather along the lines of the freakish atmospheric cocktail that spawned Superstorm Sandy, which slammed into the Mid-Atlantic coast last year. Some blame climate change, others an unlucky weather cycle. Either way, notes Jon C. Ogg at 24/7 Wall St., the forecast "is not good news for those of us who live within 50 to 150 miles of the coast in the Gulf of Mexico or along the Eastern Seaboard."

How bad do things look out in the Atlantic? NOAA says there's a 70 percent chance of an above normal hurricane season, and only a 5 percent chance of a below normal season. That's because the west African monsoon is wetter and warmer than the historical average, so we can expect to see more thunderstorms than usual churning west from Africa into the Atlantic. Those storms can strengthen and become hurricanes when they move over warm ocean waters, and the probability that they'll strengthen will be increased this year, because water temperatures in the Atlantic are higher than usual.

Another factor is that the waters of the Pacific are cooler than usual this year. That means no El Nino — a phenomenon that reduces hurricane activity in the Atlantic.

There's some comforting news buried in NOAA's announcement, though. The agency is offering a range of the number of storms that could develop — not how many will hit land. So there's always a chance that the worst storms won't hit shore.

Still, emergency management officials say people in vulnerable areas should work to ensure they'll remain safe if a powerful hurricane barrels ashore. "This is a very dangerous hurricane season, and if you're not prepared…you're likely to be a statistic," Joe Nimmich, who leads response and recovery for the Federal Emergency Management Agency, tells The Wall Street Journal.

The worst part of hurricane season, as usual, is expected to hit in August and September, so NOAA will update its projections in early August.

"With the devastation of Sandy fresh in our minds and another active season predicted," acting NOAA administrator Kathryn D. Sullivan tells The New York Times, "everyone at NOAA is committed to providing lifesaving forecasts in the face of these storms and ensuring that Americans are prepared and ready ahead of time."
